One of the first things you’ll have to learn when starting school has nothing to do with the subjects — it’s how to write an email to a teacher. Even though it may appear easy at first glance, properly putting together a formal email isn’t that simple.

We collected the most valuable tips to help you create the perfect email in no time. What’s more, here, you’ll also find the answers to some of the most common questions about properly addressing a staff member and email structure.

How to Email a Teacher

When writing a formal email for the first time, it’s normal to be confused about addressing a teacher or what kind of tone to use. While some of the information only your teacher can provide, we can recommend some general tips to follow.   

Proper email structure and writing style will get you the information you need, leave a good impression, and even make you stand out in class.

1. How to Start an Email to a Teacher


Teachers are very busy, and they receive a ton of emails daily. That’s why the first thing you should consider when writing an email is the subject line. It has to clearly state the purpose of your email, instead of something vague like a question or a greeting. 

It’s smart to write the name of the course you’re attending if you’re emailing a teacher who has different classes and then specify the exact reason for contacting them. You should make the subject line detailed but as short as possible, ideally, under ten words.

Then, you can address your teacher with “Dear” and their formal name unless they’ve instructed you to use their first name. When reaching out to a teacher you haven’t met, it’s best to stick to formal greetings.

2. How to Address a Teacher in an Email

You should always use a formal greeting when writing to a teacher. Start the email with “Dear” and address them by the appropriate title — Mr, Mrs, Ms, Dr, or Professor. If you’re uncertain how to address them, check the staff page on the institution’s official website.

It’s best to use their last name instead of first. However, if your teacher has instructed you or the class to address them informally, you can do that as well. But, when in doubt, always opt for the formal tone.

3. How to Format an Email to a Professor


A clear subject line and formal greeting are the first important parts of your email. Then, introduce yourself and mention the class you’re attending in one sentence. It’s best to keep your text as brief as possible, so you should quickly get to the point.

State the reasoning for contacting them in two or three sentences. After that, you can thank them for their time and wish them a nice day. End the email by signing your full name, and don’t forget to proofread before sending it.

4. How to Write an Email to a Potential Ph.D. Advisor or Professor


Before you email a potential Ph.D. advisor or professor, you should think about what makes you stand out from the rest of the students. It’s best to do some research on the advisor’s resume and expertise and consider the qualifications they want from their mentees.

You’ll need a clear subject line and formal greeting with Dr or Professor when emailing teachers for such purposes. It’s also important to state your name, degree, previous research, and GPA.

Then, take the parts of your resume that match their expectations and use them to get their attention. You should briefly explain your plans and goals and why you’re interested in the particular topic.

To show the professor that you’re serious and dedicated, research their work and include a few sentences on why you want them as your advisor. Before you politely finish the email, you should ask for a meeting to further discuss the mentorship.

5. How to Write an Email to a Professor for Graduate School Admission

In many cases, writing an email to a professor for a graduate school admission won’t be necessary. Committees evaluate the candidates for most programs, and professors don’t have a say in who gets in.

However, in some faculties, professors can provide an input into the admissions. So, before you write the email, you should research the application process. 

This email to a teacher format will be longer than the standard inquiry, as you’ll need to explain the motivation behind your decision to enroll in a particular program. But, the text should still be as concise as possible.

Introduce yourself in two or three sentences and highlight the aspects of your resume that are most relevant to the subject you’ll be studying. Inquire whether they’re accepting students and show how passionate you’re about the topic and your eagerness to learn.

Mention your background and interests and ask for advice or additional information about the program’s admission process. You should thank the professor for their time and end your email with a formal salutation. 

6. How to Email a Teacher About an Assignment


When emailing a teacher about a specific assignment, your tone should be professional. You’ll need to keep it formal and as brief as possible. It’s best that you write the course name and your query in the subject line.

You should mention your name and the class you’re part of. Then, you can move to the purpose of your email. Use all tips on the proper email format to a teacher we explained above — formal greeting, clear reason for contacting them, and polite ending. 

Remember always to proofread your text and use your professional email address. However, you should write to your teacher only as a last resort. First, discuss the issue with your classmates and do some research on the matter, and if you still can’t find the answer, email them.

7. How to Write an Email to a Professor About Missing an Exam


If you missed an exam, it’s necessary to contact your professor and inform them about the situation. As with other similar emails, you need to have a clear subject line and a polite greeting.

Begin by stating your name, the class you attend, and the date of the exam you missed. You should apologize, explain your absence, and offer a possible solution. If you have proof, such as a doctor’s note, you should attach it to the email.

If you know in advance that you’ll miss the exam, it’s best that you inform your professor. It’ll look more professional and might give them a chance to offer you alternative solutions to the problem.

8. How to End an Email to a Teacher


We already mentioned that you should keep the tone of the email to a teacher as formal as possible. Consequently, your sign-off also needs to be polite and professional.

When you’re done with your inquiry, thank your teacher for their time and wish them a good day or weekend. Phrases like “kind regards,” “sincerely,” or “all the best” are always a safe choice. Lastly, use your full name when you sign off.


One of the essential things you learn in school is how to talk to different kinds of people. An email to your friend won’t be the same as the email format to a teacher. Luckily, the rules and tips for formal writing are simple and easy to follow.

When addressing a staff member from your educational institution, you should always be formal, polite, and respectful. It’s also important for your email to be concise. That way, you’re guaranteed to get your answer and leave a good impression.
